Creating interpretations based on facts is either a long methodical process of searching for facts and putting them together into interpretations. If you are a researcher with a very specific niche this makes sense.
For the rest of us who are just creating our PBOK (Personal Bodies of Knowledge), we don’t have the time for that approach.
When I am creating interpretations oftentimes I have a rough idea of the facts that support the interpretation. These could be facts that I remember hearing, or facts that make sense, or facts that I have heard from other people. The point is that these are unverified facts.
When I create my interpretations with the associated facts I flag those facts as assumptions. When the interpretation gains importance, I can then spend the time to verify the facts.
Having my interpretations in Obsidian makes this process very easy, I just find the interpretation and it lists the associated verified facts and the associated facts that are fagged as assumptions.
